The Maybach W 5 SG were luxury class cars with six-cylinder in - line engines , which were built in numerous variants from 1928 to 1929 by Maybach-Motorenbau in Friedrichshafen on Lake Constance.
With the old luxury brand Maybach of the 1930s, buyers had almost all options for having their vehicle "body" according to their individual requirements and personal style.
The vehicles are considered to be the further development of the Maybach W 5 and had, as additional equipment, an "overdrive gear" (SG) based on the Maybach deflector claw , which could be operated with a lever. In addition, they had the two-speed planetary gearbox adopted from their predecessor as a manual transmission .

description
The car was developed as a further development of the previous model with an additional high-speed gearbox in order to save fuel and reduce noise even when driving at higher speeds over a longer period of time.
The basic equipment included a double friction clutch without a clutch pedal, operation of the uphill and reverse levers with the foot and a 2-speed planetary gearbox. This gearbox construction made driving easier because the steering wheel did not have to be released to shift gears. It was only shifted by preselecting a gear with the foot pedal and briefly releasing the gas and accelerating again. The engine was so elastic that it could start the car even in direct gear on gradients of 4%. At the time, the direct connection was also common for rail vehicles with mechanical power transmission .
The overdrive was the possibility to reduce the direct gear again to the gear ratio of 0.63, and was located in a separate gear after the planetary gear. To operate it, the power transmission had to be briefly interrupted, a lever next to the driver's seat pulled and then accelerated again. The transmission shifted automatically based on the Maybach rejection claw .
